Suppose labor is available to a firm at a cost of $12 per hour. Also suppose that employing another hour of labor adds 5 units to output and that any amount of output can be sold for $10 per unit. An additional hour of labor would add $50 in additional revenue to the firm. (Enter your response as a whole numer.) This firm should hire more labor. Now suppose that the last hour of labor hired by the firm has a marginal product of 4 units of output. The marginal revenue product of labor is now $ (Enter your response as a whole numer.)

Suppose you are considering hiring another worker. Also assume that you are at a firm that is operating at a point where the marginal product of labor is 5 and the price of each unit of labor is $2, and the marginal product of capital is 20 and the price of each unit of capital is $10. Should you hire another worker? If you hire another worker, what will happen to the marginal product of labor and why?
Suppose a firm is producing 2,475 units of output by hiring 50 workers (W = $20 per hour) and 25 units of capital (R = $10 per hour). The marginal product of labor and marginal product of capital are 30 and 15, respectively. Is the firm minimizing the cost of producing 2,475 units of output? Explain.
True or false and explain Suppose a firm’s marginal product of labour is MPL = 10/L, where L is measured in labour hours, the price of the product is $600, and the cost per hour of labour is $30. The firm currently employs 150 labour hours. In order to maximize the firm’s profits in the short run, the manager should increase its labour employment by 40 labour hours.
Suppose that labor is the only input used by a perfectly competitive firm. The firm’s production function is as follows: Number of Workers: 0, 1, 2, 3, 4, 5, 6, 7 Units of Output: 0, 7, 13, 19, 25, 28, 29, 29 a. Calculate the marginal product for each additional worker. b. Each unit of output sells for $10. Calculate the value of the marginal product of each worker. c. Compute the marginal profit if the wage is $100 a day. 2. Your enterprising uncle opens a sandwich shop that employs 7 people. The employees are paid $12 per hour, and a sandwich sells for $6. If your uncle is maximizing his profit, what is the value of the marginal product of the last worker he hired? What is that worker’s marginal product?
A manager hires labor and rents capital equipment in a very competitive market. Currently the wage rate is $7 per hour and capital is rented at $11 per hour. If the marginal product of labor is 65 units of output per hour and the marginal product of capital is 55 units of output per hour, should the firm increase, decrease, or leave unchanged the amount of capital used in its production process? O The firm should leave capital unchanged. O The firm should increase capital. O The firm should decrease capital.
. In the short run, labor is a hat-making firm’s only variable input. Wage rate is $5.00/hour. The firm currently employs a certain amount of labor H (hours), such that the marginal product of labor is 10 hats per worker-hour, and average product is 15 hats per worker-hour. MPL(H) = 10; APL(H) = 15. (Note: marginal and average products of labor for this firm are not constant. 10 and 15 are their values at a particular point, H, not everywhere.) What is the marginal cost of a hat for that firm?

A small specialty cookie company, whose only variable input is labor, finds that the average worker can produce 100 cookies per day, the cost of the average worker is $32 per day, and the price of a cookie is $1.00. Is the firm maximizing profit? The firm O A. is not maximizing profit because the marginal revenue product of labor is greater than the wage. O B. is not maximizing profit because the marginal revenue product of labor is less than the wage. O C. is maxinmizing profit because the marginal product of labor is greater than the wage. O D. is not maximizing profit because the price of the output is not equal to the wage. O E. is not maximizing profit because the marginal product of labor is greater than the wage.
13. You run a fried chicken restaurant in Kentucky and can hire labor at a wage of $2/hr in a competitive labor market. You don't have any costs aside from the labor because, like Joe Exotic, you get free expired meat from a grocery store. I won't tell your customers. The chicken sells for $1.50/piece in a competitive fried chicken market. The production function is shown in the following table: L (hours) Q (pieces) 1 2 7 3 10 4 11 What is the marginal product of the 3rd hour of labor? pieces of chicken (continued) Based on the table how many hours of labor should be hired in order to maximize profit? а. 1 b. 2 с. 3 d. 4
